The percent of oxygen by mass in 0.370 kg trinitrotoluene?
To find the percent of oxygen by mass in trinitrotoluene (TNT), you need to know the molecular formula of TNT. TNT contains 30.4% oxygen by mass, so in 0.370 kg of TNT, the mass of oxygen would be 0.370 kg * 0.304 = 0.11248 kg. To convert this to a percentage, divide the mass of oxygen by the total mass of TNT (0.370 kg) and multiply by 100 to get 30.4%.
How many atoms are there in trinitrotoluene?
Trinitrotolune, TNT, has the molecular formula of C7H5N3O6, so in one molecule of TNT there are 21 atoms. Of course, the number of atoms will change as the amount of TNT changes.
How do you find the mass of a single molecule?
To find the mass of an atom you divide the constant known as Avagadro's number 6.022X10^23 by the amu of an element. So lets take oxygen for example. The amu of Oxygen is " 15.99" , so you would divide 15.99 by 6.022X10^23. By doing this you will get the mass of one Oxygen atom.
What is the molar mass of a molecule?
The mass of one mole of substance, usually in grams or kilograms
Can Atomic mass be used to determine molecular mass?
Yes, the accumulation of atomic masses of the atoms within a molecule is the molecule's molecular mass.
What is the mass of a single molecule of water?
- calculate the molecular mass of the substance from the atomic weights of the contained elements - 1 molecule gram of any substance contain 6,023 141 79.1023 molecules (Avogadro number) - mass of a single molecule is: Molecular mass in grams/Avogadro number

Why the mass of hydrogen molecule is greater then the mass of hydrogen atom?
The mass of a hydrogen molecule is greater than that of a single hydrogen atom because a hydrogen molecule consists of two hydrogen atoms bonded together. When two hydrogen atoms bond to form a molecule, they share electrons, resulting in a decrease in the individual mass of each atom. However, the total mass of the molecule is slightly higher due to the binding energy that holds the atoms together.
How heavy is a cubic meter of TNT?
A cubic meter of TNT has a mass of about 1650 kg.
What is the Mass of a sulfur trioxide molecule?
The molar mass of sulfur trioxide (SO3) is approximately 80.07 grams per mole. This means that a single sulfur trioxide molecule has a mass of about 80.07 atomic mass units.
How many atoms are there in trinitrotoluene?
Trinitrotolune, TNT, has the molecular formula of C7H5N3O6, so in one molecule of TNT there are 21 atoms. Of course, the number of atoms will change as the amount of TNT changes.
What is a group of symbols that show the kind and number of each element in a single unit of a molecule called?
Mass
What is the mass percent composition of an element in a molecule?
Percentage composition= (mass of the element/mass of the molecule)*100 The fraction of the molecule's mass that comes from the element's mass
How do you find the mass of a single molecule?

What would be the unit to use to measure a single molecule?
the term gram molecule was used in chemistry and this unit is used to measure a single molecule in gram molecule.
What is the mass of a single ammonia molecule?
It is not typical to refer to the weight of literally a single molecule (one nitrogen and four hydrogens) but to a "mol" or 6.022 x 10^23 molecules. But, if that is actually what you mean, the mass of a single molecule of NH4 can be determined like this. [(molar mass N x 1) + (molar mass H x 4)] / (6.022 x 10^23) that will give you the answer in grams. [(14.01)+(1.01 x 4)]/(6.022 x 10^23) = (18.05)/(6.022 x 10^23) grams i don't have a calculator, plug it in and you've got it!
